rb26dett 2.7L stroker kit

[blk180]

OK can someone tell me what the two rb26 kits are rated at on this site i think its 800ps for the frist one and 1200ps for the next is correct and are these figures at the wheels or engine

I think you might find that it's not just the crank that gives the extra stoke but also the combination of the piston height and conrod length.

The displacement was messured and was found to be just over 2.7ltr.

I'll have to check whether my rods a standard length or not.

Regarding compression, both my head and deck where milled to accomodate the setup the mechanic is seeking.

I think you will find that it is the crank, and crank only that affects stroke. Pistons suited to stroker cranks will measure less form gudgeon pin to crown to avoid making contact with the head / valves and meeting the desired level of compression. If you have a standard crank and you increase the rod length by say 2mm, the piston will travel 2mm higher at tdc (and would require either a sandwhcih plate or very thick head gasket) but remember it wll also be 2mm higher at bdc. Using your volumetric equation the capacity will remain unchanged. It appears with the kit you have purchased that your gain in capacity is due to the O/S pistons only.

A couple of useless things on Jap stroker kits

1) they all use the standard length rod

2) the difference in the "cheap" low horsepower kit vs the "expensive" high power kit is mainly the pin size(21mm std vs 22mm "SPL").

3) Merli's running big block chev pistons in his new motor to give him a displacement of 8 liters.

Fact or fiction?

Goddammit DoughBoy, you weren't meant to tell everyone that! RB80 > RB30 with RB26 Head :wassup:

And MrCharms, I only resort to smart-ass comments when I have to repeat myself 4 times, only to be ignored blindly and be replied to with completely wrong information over and over again.

There's only so many times I can try to tell you what's really going on with your engine (based on information you've supplied to me), before I give up and try to take the piss

In any case, refer to my volumetric measurements on the first page, you're making just over 2650cc, which bumps you up to 2.7 Litres

P.S. If you sat down for a minute before replying and visualised what goes on in a piston engine, you'd quickly realise that crankshaft design is the ONLY thing that will effect stroke length. It's pretty simple when you think about it

anyone got a kit lying around for sale

[BU5TER]

I'm pretty sure Doughboy has one from memory its about $11k

If the block is going to crack, I honestly don't think 1mm is going to save you.

I think it would if it were a 20'thou sleeve

And yes, I was pretty proud of myself that I remembered how to calculate volume of a cylinder without looking it up :Oops:

Hey old buddy doesnt suprise me one bit ! the subject of "Stroking" would be right up your alley.

Hows that car going anyway ?
